JAMES A. OUTTEBSON, OF CARTHAGE, NEW YORK.

OARGO-DISCI-IARGING MECHANISIW.

T 0 all whom it may concern Be it known that I, JAMES A. OUTTERSON, a citizen of the United States, and a resident of Carthage, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in Cargo- Discharging Mechanisms, of which the fol lowing is a specification.

This invention relates to cargo discharging mechanisms and has for its object to provide means of the class specified, simple in construction and rapid and eflicient in operation.

My improved mechanism is particularly adapted for the equipment of boats of various types, and in the drawings accompanying this specification, Figure 1, is a longitudinal sectional elevation on line 11 of Fig. 2. Fig. 2 is a plan view corresponding with Fig. 1. Fig. 3 is a cross-sectional elevation on line 33 of Fig. 2, and Fig. 4: is a fragmentary view similar to Fig. 3 and illustrating some modifications of my improvements.

Before describing the invention in detail I desire to have it understood that the invention is not limited to the particular construction and arrangement of parts which I have illustrated and shall hereinafter describe, and that various changes may be made in the mechanism without departing from the spirit or scope of the invention, and that the phraseology which I employ is for the purpose of description and not of limitation.

My improved cargo discharging means is particularly adapted for discharging cargoes of bulk material, particularly such material as readily floats in water and is not injured by immersion in water. One class of such material is timber or logs in the ordinary 1 foot lengths or other lengths.

Heretofore, it has been customary to load the hold of a vessel or the separate compartments thereof, such as at and 5, with wood in short lengths. When the vessel reaches the port of discharge, the logs of such cargo are gathered together in bundles and hoisted out in slings with the usual tackle. This method of discharge is highly laborious and slow. By my improved method I am able by the introduction of water into said hold or a compartment thereof to raise the con tents to the. deck level where the individual logs or component parts of the cargo will fall or may be directed overboard into suit- Specification of Letters Patent.

alongside paratus, not shown. As illustrated in Figs.

1 and 2, said cargo hold is divided into a plurality of cargo receptacles or compartments 1, 5, by means of the usual transverse walls as 2, 6 and 7, and each compartment is provided with a discharge opening, herein illustrated as a hatch, as 31 to compartment 5. Wall 7 dividing compartment 4 from compartment 5 may be provided with passage 8 therethrough, and gate 9 for opening and closing said passage. Said gate may be provided with stem 10, having handle 11 in the upper end thereof for operating said gate.

Located in some convenient portion of the vessel such as engine-room 12 is pump 13 raving inlet pipe let and outlet pipe 35, connected therewith. Said'pipes pass through walls 6 and 7 into compartment 5, and within compartment 4 said pipes are provided with three-way valves or cocks 15, 16 respectively. The discharge end 17 of pipe 35 may be bent upwardly and the side discharge 18 from valve 16 may be similarly bent upwardly. This upward bending of said discharge portions is to utilize the force of the outward. flow of the water to assist the upward movement of the floatable cargo. Said pipes let and 35 are also provided with valves 19, 20 respectively, preferably within compartment 12. The side port of valve 19 is connected by pipe 21 with the outside of the vessel, to serve as an intake for water and the side port of valve 20 is provided with a similar pipe 22 connected with the outside of the vessel for discharge water. These several valves may be operated from the deck level by means of elongated stems, as 23 to valve 16. Valve 19 is provided with a right-angled two-way plug and valves 15, 16 and 20 are provided with T shaped threeway plugs respectively.

At or near the'deck level 30 troughs or scuppers as 21 may be provided leading fromthe edge as 25 of hatch as 31 and thence outboard. As many of these souppers as are needed or desired may be provided and they may be removable, as shown,

may be the hatch replaced whereby, when not in use, they stowed and the railing, as 32, o restored and the bulwarks 27 be into continuity in some a s where the hatch opening is shorter E'l2It1l \'L1'SGl X than the width of the YQSStl, I provide deflectors gllit'lE the cargo in its )ward movement irom the hold through said hatchway and l iind it desirable to sometimes provide one or more pipes, as 29, with their disch lgo ends pointed upwardly adjacent to the edge of the hatch opening, as shown in Thus, by connecting said pipe 29 wi h the source of water supply as pump 13, the discharge of the cargo through said hatch is facilitated.

The preferred method of operation of my improved device is as follows: in suming that cargo compartments and 5 are filled with iloatable cargo, suc as logs in convenient lengths, 1 set val a 19, 16 and 20 in the position shown in 2 and start pump \Vater is hereby taken through pipe 21 into said pump and discharged through pipe out of nozzle 17 into compartment 5. Said operation is conti zed until the contents of said compartment 5 are raised to the level indicated by water line 33, Fig, 1, when the logs may be directed outwardly through scupper as they are successively raised to that leve ihe filling of the forward con'ipartment 5 automatically depresses the forward end of the boat whereby said forward scupper or it and its opposite soupper, not shown, may be employed for directing the cargo overboard. After his compartment has been emptied valves 19 and 16 are rotated a quarter turn in anticlockwise direction, valves 15 and 20 remaining as shown in Fig. 2. lhereupon the pump is again started, withdrawing water from compartment 5 and discharging it through. outlet 18 into compartment For promptly transferring a portion of the water from compartment 5 to compartment l, at the beginning of the filling of said compartment 41-, gate 9 may be ed, thereby allowing the water to flow freely and rapidly from compartment 5 into compartment t until a uniformity of level is establis ied in both said compartments, when said gate will be closed. This use of passage 8 may be in addition to the use of t e pump or to the exclusion of said pump, as desired. Then the operation of pump 13 is continued until compartment 5 is. empt d of water and compartment 4: is filled, thereby raising the cargo of compartment a up to and a ov e decl: level where it w, ital falls, or is directed, o erb ard through soup 'pers or otherwise, desired. After said compartment l has been emptied, Valve 15 is rotated a quarter turn in clockwise direction and ralve 20 is rotated a quarter turn in anti-clockwise direction, and the pump again started. The water contained in compartment is thereby discharged over board through.discharge pipe 22.

It will be obvious that a series of more than two compartments as d, 5, may be employed, or that one compartment may be used, if desired. Also that in a vessel provided with a plurality of compartments, said compartments may be emptied in any succession desired, or all. at one time by suitably manipulating the inlet and outlet valves.
